Is tankless right for your home?

Tankless makes sense if you have a gas line capable of supporting the BTU load, run out of hot water during back-to-back showers, or want to free up basement square footage. We size the unit based on your peak gallons-per-minute, not a generic chart.

Full conversion, done right

Most Quad Cities homes need a new vent, an upsized gas line, and a condensate path. Skipping any of those is why so many DIY tankless installs short-cycle and fail early. Our installs include the full conversion to manufacturer spec — that's why our warranty is 12 years, not 2.

Operating cost vs. tank

Most families save 25–40% on water heating versus a comparable gas tank, because there's no standby loss reheating 50 gallons all night. Pair with our water softener install to extend heat exchanger life even further.

Frequently asked

How much does a tankless install cost?

Most Quad Cities installs run $4,200–$6,400 fully installed including venting and gas line work. Financing is available from $79/mo.

Will it really never run out of hot water?

Correct, as long as the unit is sized to your peak GPM. We size for the worst-case scenario — two showers and a dishwasher at the same time.

Payments from $39/month

0% APR financing available on water heaters, softeners, and sewer line work — with approved credit.

"Burst pipe at 11 p.m. on a Sunday. They answered live, gave me a 45-minute ETA, and the tech (Mike) was at my door in 38 minutes. Quoted the repair flat-rate, fixed it, and cleaned up. Easy 5 stars."

"Got three quotes for a tankless install. Davenport Plumbing wasn't the cheapest but they were the only ones who actually sized it for our gas line and explained why. Two years in, zero issues."

"Recurring main-line backups every spring. They camera'd it, showed me the root intrusion on video, and did trenchless pipe bursting in one day. My yard wasn't even touched."
